WiFi based remote temperature & Humidity monitoring without need of a PC and Phone call, SMS & Email alert : UAE

This is the latest product being supplied by us in United Arab Emirate and other  Middle East countries for monitoring of Temperature & Humidity. This is entirely WiFi based and will work on any existing WiFi net work.


Features of WiFi Temperature & Humidity monitoring system :

  • No PC connection required
  • Storage of data is cloud based on free web server
  • Email alerts if  temperature or humidity goes above limits
  • Server based SMS alert system for temperature and humidity
  • Battery back up will last for two years
  • 1 channel of  temperature and 1 channel of humidity
  • View the data on any remote PC or tablet or mobile phone with internet connection
  • setup and operate without need of a PC

Phone call, SMS and Email alert system

The system can be connected to auxiliary devices for generating Phone  call, SMS and Email alerts. The alerts will be delivered for both high and lower temperature limits. The delay duration also can be programmed.

Features of Alert System:

  1. Phone calls can be made to upto 8 operators. Upon attending the phone call, a recorded voice message can be head indicating the nature of the fault
  2. SMS alert can be delivered fo rupto 8 operators. The SMS message will indicate the locatiWifi temperature humidity loggeron and nature of the fault.
  3. Email alerts can be delivered to 4 email ids. The Email will indicate the exact temperature at the time of occurrence of the alert.
  4. Please see videos of the monitoring and alert system

  • *1 : When wireless LAN communication is used frequently, the measurement of the internal sensor may rise by around 0.3 °C.
  • *2 : When used in environments where temperature and humidity are over the values of 50 °C 75 %, 60 °C 50 %, 70 °C 35 %, and 80 °C 25 %, sensor hysteresis may fluctuate by values greater than ±1.5 %RH. Under certain circumstances, it may take some time to return to normal measurement capability.
  • *3 : The WPS feature is not available when WEP(64bit/128bit) or WPA-PSK(TKIP) is selected in Access Point Settings. If you wish to use the WPS feature, please select WPA2-PSK(AES) or disable wireless security.
  • *4 : Optional USB Mini-B Cable US-15C is required for USB communication.
  • *5 : Battery life varies depending upon the frequency of communication, wireless LAN environment, ambient temperature, recording interval, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
